Please post a screenshot of your xml structure. Make sure your xml has a root node under which you have all the child elements which will form the rows of your sap ui5 table, only then bindRows() will work.
I created an xml for the data that you have used in your example code and the structure looks like this:
<rootnode>
<element>
<Applications>WVL BOD 9212</Applications>
<PercentComplete>75</PercentComplete>
<Date_Due>6/16/2014</Date_Due>
<Testing_Due>6/23/2014</Testing_Due>
</element>
<element>
<Applications>WVL BOD 9211</Applications>
<PercentComplete>75</PercentComplete>
<Date_Due>6/16/2014</Date_Due>
<Testing_Due>6/24/2014</Testing_Due>
</element>
...
</rootnode>
The xml that you are binding to the model should have a root node similar to the rootnode tag in the above case.
Do let me know if it still doesn't work for you.
